All about chemistry Equilibrium!!!

[quatumrulesoverall]

Being aware that the thread "Chemistry 101" is overloading, I decide to open a new thread. This thread is particularly for "Chemical Equilibrium". Urging support from all of you :eek:) ::hyper:

*Mercedes Benzene: you may carry on with your chemical reaction in Chem 101. Cheers :))

*Jay-qu: Could you support me with this thread?

[Jay-qu]

I will answer any questions you have to the best of my ability, when I am able :eek:

Thx, Jay (may I call you that), but not only me, all of you please join if you are interested. Lets bombard Jay and Benzen as much questions as you can :eek: ::)

Regarding what Jay said about equilibrium constants, basically they are in 2 terms: Kc and Kp. Kc is calculated based on the concentration of the products yields over the concentration of the reactents, Kp is in the same way but in term of partial pressure(for gas).

So... did you want help with equilibrium, or did you want other people to post questions about equilibrium...:hihi:

[quatumrulesoverall]

Sorry, I just want to help, coz I am taking this modules in my school. and I want to learn from all of you as well.

[Jay-qu]

Jay, J, Jay-qu, JQ are all fine :hihi:

 

So do you want posts of general information or will there be questions that need answering?

[quatumrulesoverall]

Everthing that belongs to the topic and I am able (copy from Jay ::hihi:) :eek2:)

[hallenrm]

Oh!! Fifteen days past ans still no students! The teachers are waiting anxiously:)

[Jay-qu]

haha :hyper: "the teacher will arrive when the student is ready"

 

the students know where to find us..

Hi Babes I am back,

Got some problems with my account password. Ok guys,

I would like to reinforce the topic with an articles, please read and give comments.

The Acid-Base euilibrium.

When titrate acid-base equilibrium, you would expect 3 situation happen:

*Strong acid and strong base titration:

It would be obvious that this titration would result in salt and water with irreversible reaction.

NaOH + HCl > NaCl + H20

*Weak acid and strong base

Alright!! I am back,

Today, we gonna carry on the topic,

The most important thing to know in Chemical Equilibria is that you got to define what is acid, and base.

Today, I am gonna cover this topic. Note that, there are many way proposed by many scientist to define a base and acid:eek_big:, we would only be focus on Bronsted-Lowry Theory of Acid and Base.:doh:

A Base: is any substance that can accept a proton. For example CH3COO-

An acid is any substance that can donate a proton. CH3COOH

The acid and base are conjugate pair. Since free protons can not exist in the solution, hence there must be a proton accpetor (base) before the proton donor release its proton.

e.g CH3COOH is a conjugate acid of CH3COO- and in another way round...

:hihi:

To be continued .....

Further, the proton is simply a Hydrogen nucleus (H+).

 

the strength of an acid is measured in pH. This has been defined in the chem 101 thread, should we do it again here for completeness?
